tester [92]

Answer:

Step-by-step explanation:

x butterflies and y dragonflies

4 < x + y 《 8

x = 2y

4 < 2y + y < 8

4 < 3y < 8

Only multiple of 2 between 4 and 8 is 6

So 3y = 6

y = 2

x = 2y = 4

Find the equation of the tangent line to the curve y=2sinx
Mrrafil [7]
 Hello
f(x) = 2sin(x)
f(<span>π/6) = 1 
f'(x) 2cos(x)
f'(</span>π/6) = 2×co(π/6) = 2 × root(3)×0.5  =root(3)
The equation of this tangent line is : y= root(3)(x-π/6)+1
y = root(3)x+1 - π/6(root(x))  <span>in the form y=mx+b
m = root(3)   and   b = </span>1 - π/6(root(x))
